Title: Robot for moving job
Inventor: ISHIBASHI TAKAFUMI
IPC: A47L11/00
Filed: 1994-08-30
Abstract: PURPOSE: To accurately control the travelling of a robot by detecting only the effect of weave texture of a carpet in the straight advance travel even in the case of direction change or meandering. CONSTITUTION: A carpet weave texture detection means 24 detects a deviation angle between a travel direction and an object direction of a robot due to the effect of the weave texture of a carpet and gives the deviation angle to a control means 21. The control means 21 is provided with a convergence detection means 52 to detect it that the deviation angle is converged into a value corresponding to the straight advance travel in succession to a direction conversion of the robot or avoidance of an obstacle of the robot, and the control means 21 uses only the deviation angle after the convergence to exclude the deviation angle information other than the weave texture of the carpet resulting from the direction conversion or avoidance of the obstacle thereby controlling the straight advance travel. Moreover, the convergence is detected in the process of a 1st process by the discrimination of the deviation angle and a 2nd process by the discrimination of a time change rate of the deviation angle calculated by a differentiation means 53. Furthermore, a spin-turn means 54 or a meandering means 56 sets a reference output for the carpet weave texture detection means based on the converged deviation angle in the case of the straight advance travel in succession to a spin-turn or meandering.

Title: Production of light shielding layer for color filter
Inventor: SUDO MIKIO
IPC: G02F1/1335
Filed: 1993-08-18
Abstract: PURPOSE:To provide a process for inexpensively producing a light shielding layer which is free from pinholes and has a high light shielding effect by subjecting a conductive to an electrolytic treatment after formation thereof, then subjecting a substrate to a surface treatment with an acid, chelating agent or their combination. CONSTITUTION:The conductive film 2 consisting of an oxide is formed on the substrate 1 having a smooth surface. The substrate formed with the conductive film 2 is then put as cathode into an electrolyte and is subjected to the electrolytic treatment. A photosensitive resin 3 is electrodeposited on the conductive film if this resin is utilized as the electrolyte. The points to be formed with the light shielding layer are exposed by executing mask exposing and developing patterning. A part 4 of the components of the conductive film surface are precipitated on the surface. These parts are treated and removed by the acid or the chelating agent. The surface is thereby further reformed and the wettability is greatly improved. A plating layer 5 is then formed by executing plating and the photosensitive resin remaining in the final is finished by removing the peeled and precipitated materials. This light shielding film has the excellent adhesion property to the substrate and has the good adhesion of the conductive film and the plating as well. Light leakage by the pinholes, etc., is not admitted.

Title: Waveform shaping circuit
Inventor: MAKITA HIROMITSU
IPC: H03K5/08
Filed: 1981-12-19
Abstract: PURPOSE:To shape accurately the waveform of a periodic pulse signal accompanied with level change, by changing the reference voltage, which slices the periodic pulse signal to shape the waveform, in accordance with the periodic pulse signal. CONSTITUTION:In an engine analyzer, the ignition coil signal from an input terminal 1 is supplied to an LPF2 having, for example, a low cut-off frequency of 1,3kHz. The LPF2 attenuates the noise included in the coil signal, and the output signal is supplied to a comparator 3 and a reference voltage generator 4. The generator 4 generates a reference voltage having a level corresponding to the input signal, for example, a voltage indicating the average level of the input signal and supplies this voltage to the comparator 3. In the comparator 3, the output signal of the LPF2 is certainly sliced by the reference voltage because the  reference voltage is changed in accordance with the change of the output signal level of the LPF2 even if the output signal level of the LPF2 is changed by the frequency or the duty ratio of the input signal, and thus, a waveform-shaped ignition coil signal is obtained in an output terminal 5.
